Supercritical Carbon Dioxide(SCCO2)-Mediated Intercalative Polymerization of Conducting Polyaniline-Fluorinated Montmorillonite(PANI-FMMT)
Many investigators have demonstrated the feasibility of polymerization in SCCO2, but SCCO2 is always employed as “alternative” or “green” solvent，instead of “effective” medium. In fact, SCCO2 offers mass transfer property advantages over&...

Encapsulated Cadmium Sulfide in Silicon Dioxide Porous Shells for Enhanced Photocatalytic Sustainability and Commendable Protection of Organic Carriers
关键字：protection，adsorption，catalysis
AbstractThe purpose of this study is to provide a solution to two troublesome problems on photocorrosion of cadmium sulfide (CdS) and photocatalysis damage to organic carrier. An encapsulation system of CdS in silicon dioxide (SiO2) porous shell can be constructed by following strategies: polyporrole (PPy) layer is deposited on the surface of CdS nanoparticles via chemical redox polymerization; th...
